STATIONARY INSPECTION
The quality assurance of wheelset press fits relies industry-wide on the press-fit curve. It is reliable with proven materials, but reaches its limits during development and adaptation of new components. The Zyglox sensor reveals force relationships in the material that conventional methods overlook.
// CASE STUDY
5 WHEELSETS. 1 HIDDEN DEFECT.
In a blind study, five wheelsets were examined with the Zyglox Stationary Inspection sensor. We were able to identify the defective wheelsets — even though the documented press-fit curve and behavior during assembly were completely normal in all cases.
THE LIMITS OF THE PRESS-FIT CURVE
CONVENTIONAL PRESS-FIT CURVE
Only documents the force-displacement curve during assembly. The actual final state of the material remains a black box.
ZYGLOX STRESS MAPPING
Measures force relationships after pressing. We make the actual contact pressure in the steel visible — contactlessly.
Maximize Safety
Measuring contact pressure provides certainty about the correct fit of wheelsets.
Reduce Maintenance Costs
Detect hidden defects during assembly, before the wheelset causes expensive repairs in operation.
Easy Handling
Supplement your existing processes with a method that reliably validates actual contact pressure in just 20 minutes per axle.

THE TECHNOLOGY BEHIND THE ZYGLOX SENSOR
THE VILLARI EFFECT (MAGNETOSTRICTION)
Our Hollow Shaft Sensor (HSS) utilizes the active inverse magnetostrictive effect. Your advantage: You can measure contact pressure in steel with high precision and completely contactlessly. The component remains undamaged while you gain insight into material stresses.
ACCURACY: < ± 1.5% FUGENDRUCK
INTEGRATION: NON-DESTRUCTIVE (NDT)
DETECTING REAL STRESS DISTRIBUTION
While the traditional press-fit curve only documents the assembly process, the Zyglox sensor measures the actual final state. You can see exactly how mechanical stresses are distributed in the component after pressing.
